At this point, the Offspring are accustomed to universal success. In a career already filled with a multitude of milestones and accolades, the Orange County-based rockers turned 40 this year, joined Spotify’s Billions Club, released their 11th album, “SUPERCHARGED,” and charted yet another No. 1 single.

But it wasn’t always so easy. Initially floundering in a Southern California punk scene that included Bad Religion, Circle Jerks, Black Flag, and NOFX, the Offspring’s first decade together brought them to the brink of giving up.

“Nobody cared for the first ten years,” lead guitarist Brian “Noodles” Wasserman said from a recent promo stop in New York City. “It wasn’t until 1994, when (third studio album) ‘Smash’ came out that we were all able to quit our jobs and do this full time. And we never thought we’d be doing it for this long or this successfully. It’s mind-blowing. It really is.”

Released on Epitaph Records, “Smash” has now sold more than 12 million copies, stands as the best-selling album released by an independent record label, and has achieved platinum status in at least 10 countries. And that was only the beginning.

The band has since secured four No. 1 songs on the Alternative Airplay Chart and six No. 1 songs on the Active Rock Chart. And earlier this year, their single “You’re Gonna Go Far, Kid,” from the 2008 album “Rise and Fall, Rage and Grace,” reached 1 billion streams on Spotify. Not far behind, the band’s 1998 single, “The Kids Aren’t Alright,” is poised to make the Offspring two-time members of the popular streaming service’s Billions Club — likely before the close of 2024.

This year also has seen the band team with a pair of disparate artists — one that they’ve always looked up to and one that has always looked up to them. Rock legend Brian May of Queen recently joined the Offspring for two songs during the Starmus Festival in Slovakia. And a few days later, pop superstar Ed Sheeran, who has an Offspring tattoo and claims the first album he ever owned was by the band, joined them on stage at Napa Valley’s Bottlerock Festival.

“We gave a lot of thought about getting to play with Brian May,” said Wasserman. “He is one of our absolute heroes. But we’ve also been asked a lot about playing with Ed because he said that we’re one of his heroes. It’s humbling to hear that sort of thing. And it’s hard to take that on. But I know what music means to me and how it can affect you and change your life for the better. I guess I just still find it a bit hard to process. But we are flattered and humbled with all of it.”

Far beyond the two festivals that provided those memorable moments, The Offspring has spent much of this year on the road gearing up for the October release of their 11th studio album, “SUPERCHARGED.” Produced with longtime collaborator Bob Rock, Wasserman believes the new album helped the band find a new headspace after toiling through their last project during the COVID-19 pandemic.

“It’s far more upbeat,” he said. “Not a downer like the last record. We were in a good spot. We got through the pandemic … And there was still plenty of stuff left to rail against. There is so much disheartening and frustrating stuff that happens in the world. But I’ve always felt really good about this one. We knew we were onto something strong.”

Apparently, fans agree. The new albums’ first single, “Make It All Right,” already hit the top spot on Billboard’s Rock and Alternative Airplay chart.

The band has pretty much shut things down for the year to prepare for nearly nonstop touring of the album in 2025. That’s perfect timing for Wasserman to spend some time with his recently born, very first grandchild. But they will be playing two final headlining shows this year — one in Australia and one in San Diego Nov. 16 at the Punk in the Park Festival with longtime friends Pennywise and Face to Face. Also featured on the San Diego concert bill are Streelight Manifesto, Manic Hispanic, Voodoo Glowskulls, Buck-O-Nine, Slaugherhouse and Winterhaven.

And while they’ve seen good friends in other bands like Sum 41 and NOFX call it quits recently, for the Offspring that isn’t likely to happen anytime soon.

“We talk about all the possibilities,” said Wasserman. “Always. Tours, all the places we want to go, what records we want to do next, all of it. But we’ve never had a serious talk about ‘the end.’ We’ve never talked about what calling it quits would look like or how that would happen. And we’re going to hit touring over the next year really, really hard. We can regroup after that and talk. And we may not want to tour for a while. But we’ll definitely still be recording and doing other things as well.”
